Answer:
The outside diameter of schedule 40 black iron pipe is typically larger than the pipe’s nominal size. To be precise, the outside diameter is not a fixed amount larger than the nominal size across all sizes of pipes. It varies depending on the nominal size of the pipe. For example, for a nominal pipe size of 1 inch, the outside diameter is 1.315 inches1. Therefore, the correct answer would be:
C. ¼ inch larger than the pipe’s nominal size.
This is a general approximation, as the actual difference may vary slightly based on the specific dimensions and manufacturing standards. It’s always best to refer to detailed specifications for the exact measurements.
